Fractal Engine

Fractal Engine
Turns cookies into even more cookies.
Initial Price	310 quadrillion
Base CpS	150 billion /sec
Max CpS	150 billion × 2.515 × 1.07 × (1 + C/1,000) × (1 + Pr/1,000) × (1 + Iv/20) × (1 + G/1,400) /sec Where: C – number of Cursors; Pr – number of Prisms; Iv – number of Idleverses; G – number of Grandmas.
Introduction	v2.016

The Fractal Engine is a building added in the feedback loop update. It is the sixteenth building in the game, costs 310 quadrillion cookies and produces 150 billion CpS by making cookies into even more cookies.

	Metabakeries	Own 1 fractal engine	3.1 quintillion	Fractal engines are twice as efficient. "They practically bake themselves!"	522
	Mandelbrown sugar	Own 5 fractal engines	15.5 quintillion	Fractal engines are twice as efficient. "A substance that displays useful properties such as fractal sweetness and instant contact lethality."	523
	Fractoids	Own 25 fractal engines	155 quintillion	Fractal engines are twice as efficient. "Here's a frun fract : all in all, these were a terrible idea."	524
	Nested universe theory	Own 50 fractal engines	15.5 sextillion	Fractal engines are twice as efficient. "Asserts that each subatomic particle is host to a whole new universe, and therefore, another limitless quantity of cookies. This somehow stacks with the theory of nanocosmics, because physics."	525
	Menger sponge cake	Own 100 fractal engines	1.55 septillion	Fractal engines are twice as efficient. "Frighteningly absorbent thanks to its virtually infinite surface area. Keep it isolated in a dry chamber, never handle it with an open wound, and do not ever let it touch a body of water."	526
	One particularly good-humored cow	Own 150 fractal engines	155 septillion	Fractal engines are twice as efficient. "This unassuming bovine was excruciatingly expensive and it may seem at first like you were ripped off. On closer inspection however, you notice that its earrings (it's wearing earrings) are actually fully functional copies of itself, each of which also wearing their own cow earrings, and so on, infinitely. It appears your dairy concerns will be taken care of for a while, although you'll have to put up with the cow's annoying snickering."	527
	Chocolate ouroboros	Own 200 fractal engines	155 octillion	Fractal engines are twice as efficient. "Forever eating its own tail and digesting itself, in a metabolically dubious tale of delicious tragedy."	528
	Nested	Own 250 fractal engines	155 nonillion	Fractal engines are twice as efficient. "Clever self-reference or shameful cross-promotion? This upgrade apparently has the gall to advertise a link to orteil.dashnet.org/nested, in a tooltip you can't even click."	529
	Space-filling fibers	Own 300 fractal engines	155 decillion	Fractal engines are twice as efficient. "This special ingredient has the incredible ability to fill the local space perfectly, effectively eradicating hunger in those who consume it! Knowing that no hunger means no need for cookies, your marketers urge you to repurpose this product into next-level packing peanuts."	530
	Endless book of prose	Own 350 fractal engines	155 undecillion	Fractal engines are twice as efficient. " "There once was a baker named [bakeryName]. One day, there was a knock at the door; [bakeryName] opened it and was suddenly face-to-face with a strange and menacing old grandma. The grandma opened her mouth and, in a strange little voice, started reciting this strange little tale :"	531
	The set of all sets	Own 400 fractal engines	1.55 tredecillion	Fractal engines are twice as efficient. "The answer, of course, is a definite maybe."	532
	This upgrade	Own 450 fractal engines	15 quattuordecillion	Fractal engines are twice as efficient. "This upgrade's flavor text likes to refer to itself, as well as to the fact that it likes to refer to itself. You should really buy this upgrade before it starts doing anything more obnoxious."	676
	A box	Own 500 fractal engines	155 quindecillion	Fractal engines are twice as efficient. "What's in that box? Why, it's a tiny replica of your office! And there's even a little you in there! And what's on the little desk... say - that's an even tinier box! And the little you is opening it, revealing an even tinier office! And in the tinier office there's- Hmm. You can think of a couple uses or this."	714
	Multiscale profiling	Own 550 fractal engines	1.55 septendecillion	Fractal engines are twice as efficient. "Did you know that eating a cookie means the intestinal flora inside you is eating it too? Trillions of tiny bacterial mouths to feed, each with their own preferences. Surely this is room for flavor optimization. And then, of course, there's also the much bigger things that, in turn, eat you."	757
	The more they stay the same	Own 600 fractal engines	15.5 octodecillion	"Fractal engines are twice as efficient. "Exhausted by your fractals department and its obsession with self-similarity, you've decided to take a break and seek things in life entirely disconnected from any other; alas! You find the task impossible, for all things in this world relate to all others - in each cookie, the structure of the universe; in each person, their fellow man. Cor blimey, you can't even look at broccoli in peace.""	854

Trivia

• Most of the prices for fractal engine upgrades have to do with the number 155, which is also associated with the Catalan crisis. However, this is almost certainly a coincidence due to the scaling of tiered building upgrades.
  • This excludes the upgrade "Metabakeries", at 3.1 quintillion.
• This is the last building you can get for the Android version of Cookie Clicker.

• The achievement "One particularly good-humored cow" is a reference to The Laughing Cow, a brand of soft cheese popular in Europe.
• The achievement "I'm so meta, even this achievement" achievement is reference to xkcd comic no. 917.
